But, of course, the agricultural sector, though not given the proper recognition and the required investment is one sector that contributes seriously to the development and dependence of most nations .
No matter how blessed a country is with oil minerals, if its agricultural sector isn't working and she has to rely on other country for her food and agricultural resources then in event of war or political differences they might suffer.
Agriculture vs oil, which is the big deal when it comes to the economic strength of a country?
You're comparing apples and oranges, for no meaningful outcome. Oil is a commodity extracted for purposes like energy or production of materials like plastic. Agriculture in under developed societies can require a lot of back break labor by thousands of people on covering hectares of space. However those fields in more advanced societies with technological assistance can be looked after by less than 5 people. This frees up that hard working labor pool for other more useful jobs and is what every country is aspiring towards.
